Designed to complement the many roles that the Cisco Catalyst 6500 Series plays in a network, Cisco Catalyst 6500 Series mixed media Gigabit Ethernet modules offer the broadest selection of media, densities, performance, interoperability, and chassis deployments for enterprises and service providers. These modules are ideal for gigabit Ethernet over fiber to the desktop, gigabit uplinks, aggregation of high-density 10/100 interfaces, Metro Ethernet, backbone and high-speed server farm or data center connections as well as mixed media environments supporting both fiber and copper cable connections. The Cisco Catalyst 6500 Series Gigabit Ethernet modules offer:
●Flexible configurations for any deployment: Range of port densities, media choices, and performance speeds for any deployment requirement
●Choice of media and connector type: Support multi-mode fiber or single-mode fiber using GBIC or SFP modules or MT-RJ fixed optics
Note:& For Gigabit Ethernet over Copper requirements please refer to the Catalyst 6500 series 10/100 and 10/100/1000 Ethernet interface module data sheet.
●High mixed media Gigabit Ethernet port densities: From 8 up to 48 ports per module, and up to 410 mixed media/fiber Gigabit Ethernet ports per system
●Scalable and predictable system performance: Provide a selection of switch fabric connections and throughput options: 32 Gbps, 256 Gbps and 720 Gbps bandwidth with system throughput of: 15 Mpps, 30 Mpps, 210 Mpps and up to 400 Mpps
●Operational consistency: Configurations available for Catalyst 6500 3-, 6-, 9-, and 13-slot chassis running Cisco IOS& Software and Cisco Catalyst Operating System S interoperable with all other interfaces
and forward-compatible with all Catalyst 6500 supervisor engines
●Maximum network uptime and resiliency: Support Cisco enhanced Per-Virtual LAN (VLAN) Spanning Tree Plus (PVST+) protocol, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1s Multiple Spanning Tree (MST) protocol, Per-VLAN Rapid Spanning Tree (PVRST) protocol, Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP), Gateway Load Balancing Protocol (GLBP), Cisco EtherChannel&, and IEEE 802.3ad link aggregation for fault-tolerant connectivity
●Superior traffic management: Available with large per-interface buffers and multiple-priority queues for traffic prioritization and policing, allowing for tight service-level agreement (SLA) enforcement
●Extensive management tools: Support CiscoWorks network management platform, Simple Network Management Protocol (SNMP) versions 1, 2, and 3 and four RMON groups (statistics, history, alarms, and events)
Cisco Catalyst 6500 series mixed media/fiber-based gigabit Ethernet interface modules are used in distribution and core layers, data-center and Metro Ethernet applications. These gigabit Ethernet interface modules deliver wire-speed switched connectivity and support several switch fabric connections and traffic forwarding options, these include: Classic, CEF256, dCEF256 and CEF720. With a range of port densities and modular physical layer interfaces, these modules also offer a choice of packet buffer depths for traffic shaping, and QoS granularity with varying number of queues and drop threshold options. These key features are important aspects to in determining best module for a given network application (Table 1).

Queues Legend: 1p2q2t= 1 priority queue, 2 round robin queues, 2 thresholds
The Cisco Catalyst 6500 Series Gigabit Ethernet modules support multiple queues per port for Quality of Service. Each port supports Weighted Random Early Detection (WRED) for congestion avoidance within each queue, and Weighted Round Robin (WRR) for scheduling between queues and a strict priority queue for voice traffic. Additionally, multiple thresholds can be configured to manage differentiated levels of service.
Ideal for handling mission-critical, bursty, or low latency traffic such as enterprise resource planning (ERP) or voice applications, these interface modules, including the CEF720-based WS-X6724-SFP, scale network performance and intelligent services. These modules also feature transmit and receive packet buffers and a strict priority transmit queue.
The Catalyst 6500 can aggregate up to eight physical Fast Ethernet, Gigabit Ethernet or 10Gigabit Ethernet links into a single virtual link using Cisco’s Port Aggregation Protocol (PAgP) or IEEE 802.3ad technology. This provides network managers a reliable high-speed solution for the campus network backbone.
The Cisco Catalyst 6500 Series also supports multimodule channeling technology, providing even greater resiliency by creating channels across ports on separate modules in the same chassis. As a result, connectivity is maintained even if one module (and corresponding ports) fails. This is ideal for deployments requiring scalable, flexible bandwidth within the network. An additional benefit of Cisco EtherChannel capabilities include automatic recovery and redistribution of loads ac and making the technology transparent to network applications. The same Cisco EtherChannel technology can be used across Cisco Systems industry-leading 10-Gigabit Ethernet modules, providing increased aggregation as well as resiliency against link failure.
The Cisco Catalyst 6500 Classic, CEF256, dCEF256 and CEF720 interface modules provide Gigabit Ethernet with a choice of speeds and forwarding rates.

* Mode-conditioning patch is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP/GBICs, and a short link distance (10s of meters) can cause transceiver saturation resulting in an elevated bit error rate (BER). In addition, when using the LX/LH SFP/GBIC with 62.5 micron diameter MMF, you must install a mode-conditioning patch cord between the SFP and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 300 m (984 ft).
** 1000BASE-ZX-SFP can reach up to 100 km by using dispersion-shifted SMF or low attenuation SMF; the distance depends on fiber quality, number of splices and connectors.
